Paper Abstract

Effect of magnetic nanoparticles on the transparency of a transparent matrix is studied in the infrared wavelength region. We used the iron oxide - potassium bromide system for this study. Several samples were prepared with different concentrations of iron oxide nanoparticles. IR microscopy and transmission measurements were performed to determine the resonance characteristics of aggregates of nanoparticles. We observed a sharp strong absorption peak at 7.22 μm. The amplitude of the absorption peak was dependent on the nanoparticle concentration. Effect of interface diffusion on the morphology and transmission was studied by annealing the sample at 175 C and 500C. High temperature annealing indicated interpenetration and affected the transparency significantly.
